Do you somehow think that the Cable Modem DOES NOT RUN ON ELECTRICITY???

And by the way, depending on what type of "power" requirements your computer system demands, most power back-ups are only good for 6-7 minutes of run time . . . just enough for you to properly shut-down all of your programs, or liquadate positions.

it depends on if your neighborhood cable black box(not sure the the proper name), the box that has converters going from cable to fibers. if that box uses your local power grid that also includes your home, you are out of luck there.

or, your cable provider might be smart enough to include their own power for those boxes.

If you have a power loss will your cable modem still work?

At 11am today, Bam! total meltdown. Whole neighborhood out for an hour.

I only connect one computer, one monitor, cable modem and network router to the UPS to make it last as long as possible during a power outage. My other computers, printers and non essentials are connected separately.

It the power is out beyond 1/2 hour I have a 700 watt inverter that I can connect to a running vehicle in my driveway and run an extension cord to the computer.

You can answer your own question by unplugging the power input to you cable modem right now. You'll soon find out if it still works without power. Don't forget to plug it back in before you try to post your reply.

LOL..of course I know the modem itself works on electricity...what I am asking about is the cable signal.

Phones still work with out power...blah blah. Why did I bother to ask. Just typical ET wiseass answer.

no. thats not what i mean.
lazyboy knows what I'm talking about.
and lilboy knows what i mean too.

I don't know if the modem would work...I worked for a large telecom company before the stock market and from what I remember the cable lines have relays to carry the signal.

I found exactly that happened during the great power failure of 2003, the cable internet stopped working too. I also have a dial up modem in the computer connected to a phone line which keeps working during a power failure.
